Hi,
I am trying to use the Cayenne instead of Toplink JPA (Glassfish v2), while I wait for Cayenne JPA, but I have run into a small problem.
I have created a class that extends the generated Cayenne class, and passing this between client/web and ejb with a SessionBean.
public class User extends _User implements Serializable { ..}
In my session bean I have a method for creating a new user and get all users.
public User createUser(User user) {
User newUser = context.newObject(User.class);
newUser.setUserEmail(user.getUserEmail());
newUser.setUserName(user.getUserName());
context.commitChanges();
return newUser;
}
this is working, but the values returned are all null.
The same is for getting all users.
public List<User> getAllUser() {
SelectQuery query = new SelectQuery(User.class);
List<EccUser> users = context.performQuery(query);
return users;
}
In my webapplication the result of users.size() is as expected. But when trying to list the user values it all returns null.
Does anyone have any experience with similar problems?
I was thinking of creating a wrapper class like
public class UserWrap implements Serializable {
..
the same attributes as in User
..
public UserWrap(User user) {
..
this.attribute = user.getAttribute();
..
}
But I would like not to do this as the may be many changes in the entities, and then I manually have to enter the new field in the wrapping.
Best regards
Jone Lura
